Ramsey Electronics Model No.     RRW1B 

Have you ever been frustrated with the range of your remote 
controls? Tired of having to bounce your IR remote off of 
ceilings and walls? Do you want to run your system from 
another room or floor? Here is the answer to your prayers! 
Extend the range of your remote controls through walls, around 
corners, and even from outdoors! 

The separate IR Receiver module (RRW1A) with sensitive element 
can receive your remote control’s signal up to 36 feet away before 
re-broadcasting it wirelessly! 

The receiver (RRW1B) reconstitutes the radio signal using a PIC 
micro-controller to restore noisy or weak signals and then re-
broadcasts the IR remote’s signal to your components via a wired 
high-efficiency IR LED. 

Extend the range of your remote control to greater than 100 feet 
wirelessly beyond the receive range of the IR sensor. Greater than 
300 feet with a directional antenna pair (available separately). 

Works with almost any remote control (38 kHz carrier), does not 
need to be programmed. 

Operate from 8V to 16V AC or DC. Use our AC125 wall adapters 
for long operation. 

LED indicator lets you know when you are receiving an IR signal 
or not.
